Saunders EX Diaphragms

The Silicone backing offers exceptional resistance to high temperatures compared to EPDM. EPDM rubbers suffer damage with prolonged exposure to temperature such as encountered during heat sterilization. This damage results in loss of resiliency and resistance to compression set and reduces the ability of the EPDM backing to properly energize the wetted PTFE diaphragm face.

Outstanding high temperature performance and resistance to long term exposure at elevated temperatures and ideal for steam distribution and supply, sterile barrier, and block-and-bleed applications.

Improved seal-to-atmosphere performance and reduced requirements for re-torqueing of fasteners after thermo cycling.

Saunders Passivation Diaphragm

The Saunders® Passivation Diaphragm is designed specifically for use during passivation of stainless steel systems in life science applications. This new diaphragm is a practical solution for the industry where it is common practice to replace seals and valve diaphragms after passivation. Each passivation diaphragm is equipped with a high visibility, bright yellow tag that extends outside the valve assembly, indicating that the installed diaphragm is for passivation use only. This cautionary feature reminds end-users of the diaphragm’s sole purpose, thus reducing the risk that it will be left in the system after exposure to passivation chemicals and preventing possible contamination from detritus or anodic components becoming embedded in the diaphragm face.
